Does A Mold Made Of Zero-shrinkage Resin Surely Won’t Deform?

Aug 07, 2020

The answer is impossible. As shown in the picture above, for the small mold cast with pure zero shrinkage resin, the deformation is still obvious.

Simply put, a zero-shrinkage resin is a resin with a low-shrinkage material. Compared with conventional mold resins, the shrinkage rate is still well controlled. But when it comes to mold deformation, this is not caused by a single factor. Different mold structures, glass fiber layups, curing and post-reinforcement are the keys that ultimately affect mold performance.

Don't think that the mold will not be deformed if the zero shrinkage resin is used. This is just the best effort to control the mold deformation from the material aspect.
